Ans: Volume of aspirin is 0.229 cm³
Density of Aspirin (d) = 1.40 g/cm3
Mass of Aspirin (m) = 320 mg = 0.320 g
The volume (V) of aspirin
The density of a substance is the mass occupied by it per unit volume
i.e. density = mass/volume
d = m/v
V = m/d = 0.320 g/1.40 g.cm⁻³ = 0.229 cm³
The volume of aspirin is
To calculate mass of a substance, we use the equation:
We are given:
Density of acetone =
Mass of aspirin = 320 mg = 0.320 g (Conversion factor: 1 g = 1000 mg)
Putting values in above equation, we get:
Hence, the volume of aspirin is
na + cl ⇌ nacl
balanced chemical equation:
na + 2cl ⇌ nacl2
sodium + clorine goes to form sodium chloride (table salt).
the product is nacl2.
and the reactants are na and cl.
(note: if you don’t know what ⇌ means, read below: -
⇌(double head arrow) means reversible reaction).
answer: they produce more slow than unicellular organisms.
